ROOFING.

Specification of Letters Patent.

Patented May 7, 1918.

Application led December 26, 1916. Serial No. 138,775.

To all whom t may concern:

Be it known that I, EDWIN A. MAsTIcx, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented -certain new and useful Improvements in Roong, of which thefollowing is a specification.

My invention relates to roofing materials, and has for its object the`provision of improved shingles which may be formed of part of thisspecification, and in which- Figure 1 is an isometric fragmental vie ofa rooiing construction embodying my 1nvention.

taken as on line 2-2 in Fig. l.

Fig. 3 is an enlarged perspective view of a shingle used inthe'construction; and

Fig. 4 is a perspective view of a portion of a strip used in theconstruction.

Referring'more particularly to the drawing, I have shown a roofingconstruction made up of a .plurality of members, which for the purposeof this invention I term shingles. Theseshingles may be made of anysuitable or desirable material. I find that a suitable material may beformed with a paper or pulp backing having asphalt thereon with crushedslate pressed into the asphalt. Shingles made of this construction areof somewhat flexible nature. rangement I have shown for securing them onthe root` electivel holds them in their curved orarched con 'tions Theroofk shown comprises a sheeting 5 which may be of any preferred orconventional construction. On this sheeting I preferably place awater-proof covering 6 Aof any desirable substance, such asA roofingpaper, or the like. This covering 6 may be dispensed with when the roofhas considerable pitch and the shingles .are sufiiciently lapped toprevent moisture from passing upwardly betweenxthem. On the covering 6,

or Where the vcovering is not used, on the sheeting 5, I secure strips 7which may be of wood, or any other desirable substance. The strips Amaybe nailed to the sheeting, or

The arsecured in any other desirable manner. The strips 7 are preferablyspaced at distances so that an edge portion 8 of each shingle may besecured to one of the strips 7 and the upwardly curved or arched portion9 of the shingle extend over the next adjacent strip 7 and rest on thenext shingle. With this construction, the curved or arched portion 9 ofthe shingle will be maintained in such curved or' arched condition,since the portion 8 is nailed or otherwise secured t0 a strip 7 and theedge 10 of the shingle rests in a valley 11 of another shingle. Thisprevents the edge 10 from moving away from the edge Sand holds theshingle in its curved or arched condition. I have termed the hollowgroove-like portion of the shingle between the parts 8 and 9 a valleyfor the purpose of this specification.

In order to make the shingles lie flat against one another in the roofso that substantiall no air spaces will extend between Fig. 2 is anAenlarged fragmental sectioIFA the over apped parts of the shingles, Icut away certain corners. The edge portion 8 of each shingle is cut awayat its lower end, as at 12. The lower edge 13, of the notch 12, ispreferably considerably higher than the bottom of the valley 11, so thatwater running down said valley will not run over the lower edge 13, ofthe notch 12. The notch 12 is of substantially the same length as thedesired lap in the shingles, so that if the lap of the shingles is to be'considerable, the notch 12 will be made longer than where the lap ofthe shingles is comparatively short. At the corner, diagonally oppositethe notch 12, I form a notch 14 of substantially the same length asnotch 12 and of a depth so that its top edge 15 can rest 'on the edge 13of another shingle inthe roof.

In laying the shingles in a roof, they are preferably laid in horizontalrows, although they may be laid in vertical rows when so desired. Inlaying the shingles, I preferably nail them, as at 16, in Fig. 1, to thestrips 7. It will be noted that the edge 10 of one shingle extends overthe edge 8 into the valley 11 of another shingle, so that Water willbeshed from the adjacent halves of both of such shingles into said valle11. It will be noted that the edge 13 o one shingle, such for instanceas indicated at A, in Fig. 1, is lower than the upper edge 17 of the ede portion 8 of shingle B, therefore, the ege 17 would catch any waterwhich might splash up over edge 13 and conduct suchwater downwardly`through valley 11 ofthe shingle B. lt will also be noted that when theshingle C is tted in its place, its edge will fit against edge 15 ofshingle A, andthat the edges 13 and 15 of shingles A and C will both lieon the upper end of the portion 8 of shingle D, thereby providing asubstantially watertight joint. When another shingle is placed aboveshingle A., the lower end of such shingle will overlap the edges 13 and15 of shingles C and A. respectively, further facilitating asubstantially water-tight joint.

- as at 19, of shingle Din Fig.1. The matter of nailing the shingleswill depend upon the flexibility of the materal in them and the amountof each shingle exposed to the weather. y

lin Fig. 1 I have shown the strips 7 being substantially triangular incross section, but it will be understood that these strips may be formedof any other suitable cross section. v

ln Fig. l l have "shown a portionof a strip 7 which is of rectangularcross section.

While I have illustrated and described the preferred form of myinvention, l do not-desire to be limited to the precise details setforth, but desire to avail myself of such variations and changes as comewithin the scope of the appended claims.

1. 'A roof comprising sheeting; spaced strips extending between the comband eaves of the roof on the sheeting; and shingles covering. thesheeting and strips, each shingle having a narrow portion at onelongitudinal edge disposed upwardly and y,secured to one of said stripsand the remaining portion of said shinglebeing in arched form andproviding a valley between said portions, the. arch in each shinglebeing maintained therein by the upturned edge of each shingle beingsecured against movement on the sheeting and the longitudinal edge ofsuch shingle opposite to said narrow portion being disposed in thevalley of an adjacent shingle in the same horizontal rowof shingles,there being two substantially rectangular notches in each shingle, saidnotches each being of a length corresponding to the length of the lap inthe vertical lines of shingles and the combined widths of said notchesbeing substantially` equal to the width of the narrow edge portion, oneof said notches being in theV lower end of said narrow edge portion andthe other notch being in the diagonally opposite corner of said shingletherefrom.

3. A roof comprising sheeting; spaced strips extending between the comband eaves of the roof on the sheeting; and overlapping shingles coveringthe sheeting and strips disposed in horizontal and vertical rows, eachshingle having a narrow portion at one longitudinal edge disposedupwardly and secured to one of said strips, and the remaining portion ofsuch shingle being in arched form and providing a valley between saidportions, the other longitudinal edge of said shingle being disposed inthe valley of an adjacent shingle' in the same horizontal row, therebeing two substantially rectangular notches in each shingle, saidnotches each being of a length corresponding to the length of the lap1n. the vertical lines of shingles and the combined widths of saidnotches being substantially equal to the width of the narrow edgeportion, one of said notches being in the lower end of lsaid narrow edgeportion and the other notchsbeing in the diagonally opposite corner ofsaid shingle therefrom.

In testimony whereof I `have signed my name to this specification, onthis 21st day of October, A. D. 1916.
